Times have changed since 2002, when software as a service was a curiosity of the CRM market, aimed primarily at small businesses. A complete array of providers now offers service-based versions of practically any enterprise application to businesses of all sizes. For some ideas about what is required for SaaS deployment, the author reviewed two cases: a global CRM deployment by Motorola and a service that is assisting the Humane Society to comply with Payment Card Industry regulations. The customer service unit of Motorola is a cost center because expenditures are scrutinized and resources are scarce. To save money, Motorola outsources its global call centers to local contractors that provide software, equipment, and staff. It was tough for Motorola executives to get an accurate view of customer satisfaction with Motorola products and the call center experience, so Motorola initiated XperienceCare, a three-year project to move its call centers to SaaS vendor RightNows CRM platform. The single platform will eliminate the inefficiency of collecting and processing call center records from multiple software products and will develop one knowledge base that every call center employee can access. The Humane Society has a unique constituency--10 million members who support its animal rights advocacy efforts. Security is critical, according to EIO Beverly Magda. The Humane Society was using a vulnerability management service that remotely scans consumers Internet-facing machines, including web servers, network devices, and firewalls. When she learned about the service, Magda realized that the Human Society could provide the service itself, saving time and money. Magda believes in the SaaS model for various aspects of the Humane Societys operation in order to alleviate operational burdens, reduce capital expenditures, and streamline business processes. The SaaS application delivery model is sophisticated enough to be a standard component of an IT playbook.
